新建一个“chineseurl.php”文件： 

<?php

// IIS Mod-Rewrite
if (isset($_SERVER['HTTP_X_ORIGINAL_URL'])) {
$_SERVER['REQUEST_URI'] = $_SERVER['HTTP_X_ORIGINAL_URL'];
}
// IIS Isapi_Rewrite
else if (isset($_SERVER['HTTP_X_REWRITE_URL'])) {
$_SERVER['REQUEST_URI'] = $_SERVER['HTTP_X_REWRITE_URL'];
}
else
{
// Use ORIG_PATH_INFO if there is no PATH_INFO
if ( !isset($_SERVER['PATH_INFO']) && isset($_SERVER['ORIG_PATH_INFO']) )
$_SERVER['PATH_INFO'] = $_SERVER['ORIG_PATH_INFO'];

// Some IIS + PHP configurations puts the script-name in the path-info (No need to append it twice)
if ( isset($_SERVER['PATH_INFO']) ) {
if ( $_SERVER['PATH_INFO'] == $_SERVER['SCRIPT_NAME'] )
$_SERVER['REQUEST_URI'] = $_SERVER['PATH_INFO'];
else
$_SERVER['REQUEST_URI'] = $_SERVER['SCRIPT_NAME'] . $_SERVER['PATH_INFO'];
}

// Append the query string if it exists and isn't null
if (isset($_SERVER['QUERY_STRING']) && !empty($_SERVER['QUERY_STRING'])) {
$_SERVER['REQUEST_URI'] .= '?' . $_SERVER['QUERY_STRING'];
}
}

require("index.php");

?>

修改 web.config 文件：

<configuration>
<system.webServer>
<rewrite>
<rules>
<rule name="ChineseURL" stopProcessing="true">
<match url="^(tag|category)/(.*)$" />
<action type="Rewrite" url="chineseurl.php"/>
</rule>
<rule name="wordpress" patternSyntax="Wildcard">
<match url="*" />
<conditions>
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
</conditions>
<action type="Rewrite" url="index.php" />
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>

两个文件都保存在 WordPress 的安装目录下。

若 WordPress 不是装在根目录，则需要修改“<match url=”^(tag|category)/(.*)$” />”为“<match url=”^安装目录/(tag|category)/(.*)$” />”。如果在固定链接设置里把默认的标签前缀和分类目录前缀（tag 和 category）改了，则更改这句里的对应内容即可。
